If anyone actually cares, this happens because the heat from the ball evaporates the water so fast that it creates a thin layer of air between the ball and the water. After a few seconds the ball cools enough for the evaporation to slow down and is then cooled faster as the water actually touches the ball.

What the hell are you talking about? Of course it didn't happend in super speed. They are allways switching between fast hand to hand combat, and kamehameha ETC. Why would they slow down something, when there is allready super fast combat in the episodes anyway?
